impressively polished game!
its a little difficult to line up shots with the movement, it would help if it didnt reset your direction after you were moving diagonallly, because it makes firing orthogonally way more viable
one boss spawning immediately after the last when you take too long can feel sudden when youre playing for the first time
the charging mechanic along with dashing, evolving, and big shots are all very well balance (honestly i forget about time stop and beat all the difficulties without, wouldbe been useful lol)
one more thing is i do prefer the default skin just because the different evolutions are way more visually distinct, which is very useful
but lots of juice, awesome visuals and sound effects- i love how the music and colors changes between and during boss battles, overall amazing game! hope this feedback helps :>
